Principal Kuma Kocho has sent the IChu on a summer vacation as a present. Each of them set out to make the most of their vacation on a private beach reserved just for them, but Mutsuki seems unhappy somehow. Then, one by one, people start going missing... The IChu that are left find a mansion deep in the forest and head inside to search for their friends.

!لا بدّ أنك تمزح! قم بذلك في مكان آخر

Devem estar brincando!
Façam isso longe daqui!
Нашли место! Проваливайте!
